PZ673H Pneumatic Knife Gate Valve

fe gate valve, also known as knife gate valve, knife type slurry valve, its opening and closing part is a gate, the movement direc.

Product Usage The PZ973H electric knife gate valve series products are widely used in various industrial fields, especially in mining and steel industries - used for coal, filter slurry, purification devices - used for wastewater, mud, dirt, and clarified water with suspended solids, paper industry - used for any concentration of pulp, feed water mixtures, power plant ash removal - used for professional pipeline systems such as ash slurry. Product Features 1. The electric knife gate valve has a simple structure, beautiful appearance, full diameter flow channel, and small flow resistance coefficient. When the gate is lifted, the adhesive on the sealing surface is scraped off at the same time, automatically removing debris; 2. Stainless steel gates can prevent seal leakage caused by corrosion. The overall stainless steel material prevents corrosion damage and has a long service life; 3. Various piping flange standards and flange sealing surface types can be selected, as well as various driving methods such as manual, worm gear transmission, electric, pneumatic, hydraulic, etc., to meet the different needs of users.

The PZ273H electro-hydraulic knife type gate valve controls the opening and closing of the valve through the reciprocating push position of the electro-hydraulic linkage device. If equipped with sensors or digital display devices, it can be centrally or programmatically controlled in remote and high-altitude hazardous areas. It is widely used in industries such as metallurgy, power, coal, mining, and water conservancy, and is a new and updated replacement product with strong applicability.

Pneumatic knife gate valve, also known as pneumatic knife gate valve, pneumatic knife gate gate valve, pneumatic slurry valve, and pneumatic mud valve, has a gate as its opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate that can cut fiber materials. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters, usually 5 °, The gate plate of the wedge-shaped knife gate valve can be made into a whole, called a rigid gate plate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.

Cast steel electric ball valves are suitable for two-position cut-off and adjustment situations. The connection between the valve and the actuator adopts a direct connection method. The electric actuator is equipped with a built-in servo system, without the need for an additional servo amplifier. The operation can be controlled by inputting a 4-20mA signal and a 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, and stable movement. The actuator can be equipped with electronic electric actuators such as UNIC, PSQ, HQ, DHL, or pneumatic piston actuators such as GTX and AL according to user requirements.

Product Overview: The self operated pressure regulating valve does not require external energy, and uses the energy of the regulated medium as the power source to introduce an actuator to control the position of the valve core, change the pressure difference and flow rate at both ends, and stabilize the pressure before (or after) the valve. It has the advantages of sensitive action, good sealing performance, and small pressure set point fluctuations, and is widely used for automatic control of pressure reduction and stabilization of gas, liquid, and steam media. There are two types of actuators: membrane type and piston type; There are two types of functions: post valve pressure regulation for pressure relief (B-type) and pre valve pressure regulation for pressure relief (K-type). The nominal pressure ratings of products include PN16, 40, and 64; Valve body diameter range DN20~300; There are three levels of leakage: Level II, Level IV, and Level VI; The flow characteristic is fast opening; The pressure is adjusted in stages from 15 to 2500kPa. It can be combined as needed to meet the user's working conditions.

The H41H/W lift check valve is selected for use on pipelines under various working conditions, such as petroleum, chemical, and thermal power plants, with a nominal pressure of PN1.6-6.4MPa and a working temperature of -29-550 ℃. Applicable media include: water, oil, steam, etc

Silent check valve is to rely on the flow of the medium itself and automatically open, close the disc, used to prevent media backflow valve, also known as check valve, one-way valve, silent check valve backflow valve, and back pressure valve.
